ABSTRACT:
A partially separable attachment device for sheet metal screed and stake assemblies of the type used in forming concrete ground slabs serves to hold top portions of the sheet metal screed and its supporting screed stakes in interassembled relation for use in the screed-forming of concrete slabs of large area in smaller slab sections. The attachment device has a head portion projecting upwardly of the assemblage which serves as the screeding upper edge. This head portion is torn away after setting of the adjacent slab sections to provide recesses for the placement of caulking material protecting against the entrance of moisture.
